1442340G1 Adtran Compatible 1G SFP EX 40km SMF Transceiver

The 1442340G1 is a 1G SFP built to the EX long-reach standard, carrying gigabit Ethernet up to 40km over single-mode fiber through a duplex LC interface. At that distance it fills the gap between metro-access and true long-haul optics, and it comes coded to register on Adtran platforms as a native part. Insertion is hot and needs no host configuration, with DDM available for live monitoring of the link across the full 40km reach.
